I would never turn down content for RPs sake, so yeah, I'm certainly going to experience it. Way I see it, if it exists in the game world, then it isn't really all that superstitious, is it? Hehe.
Here's a definition of superstitious:
1. An irrational belief that an object, action, or circumstance not logically related to a course of events influences its outcome.
2. a. A belief, practice, or rite irrationally maintained by ignorance of the laws of nature or by faith in magic or chance.
b. A fearful or abject state of mind resulting from such ignorance or irrationality.
c. Idolatry.
So...once you actually see a ghost or whatnot, it ceases to be a superstition.
And beyond that, it'll be fun!
